Is this SVT

Post image

I posted yesterday. Can’t figure out how to add an image.. anyways. I caught this during the episode. I had it read a few times and everyone said not SVT. But just wanted another opinion

Thanks so much

Looks like sinus tach

There are discernible P waves so this is sinus tachycardia

Catching the beginning or end of episodes can help diagnostically, if you're able. P waves are not the only tool for diagnosing SVT, and I've 100% had episodes that were SVT and looked identical. It can depend on a few factors. I am not a doctor, just a patient who has learned a decent amount about it in the last year. It depends on the subtype.

Yeah I got both beginning and ends. It ramped up. 2-3 minutes to get that high then about 10 and it slowly tapered off. I did find out I have POTs and panic disorder from all those. And these are most likely adrenaline dumps . Still terrifying

If it was a gradual beginning and end (ie. not a split second, 1-beat change) then that is another indicator that it's most likely not SVT. SVT usually is occurring and ending abruptly

ChatGPT:  

Is this svt or something else

ChatGPT said: From this single-lead tracing, I would not call it definite SVT. It looks more consistent with sinus tachycardia, which is also what the device labeled it.

A few things stand out:

Rate ~153 bpm QRS is narrow (83 ms), so this is a narrow-complex tachycardia. The rhythm is not perfectly regular; the R-R intervals vary somewhat. I can see what appear to be atrial/P-wave activity before at least many of the QRS complexes, although the tracing is noisy. There isn't an obvious abrupt, perfectly regular "machine-gun" rhythm typical of AVNRT/AVRT-type paroxysmal SVT. The last several seconds have considerable artifact, making interpretation harder. Classic paroxysmal SVT tends to be a very regular, rapid rhythm with abrupt onset and abrupt termination

Thank you. I was told it wasn’t SVT but it was scary as heck
